Tentacruel is one of my favorite pokemon.
I struggled with how I hoped to attach so many tentacles until it hit me-- I'm using clips. Every clip adds three more places to clip onto. They perpetuate each other. THEY ARE UNSTOPPABLE! VIVA LA CLIPS!
It's a little hard to tell how big Tentacruels are because of the tenacles, but I'm pretty sure this is minifig scale judging by the person-pokemon size comparison diagram in my pokedex.
This vig is the same one I used for Mantine, so judges for the club shouldn't award any extra points for it. Watch out, Goldeen, Tentacruel's not as peaceful as Mantine was!
